Replaced my upper radiator hose which had a complete failure. However, I always like to double check the system when replacing a hose (something other than wear and tear usually is the culprit). Sure enough, I have a small leak coming out of the valve cover gasket on firewall side. The time it took me to find the leak, not sure if replacing the gasket is a job to tackle in my garage. Any pointers on replacing the gasket and other issue which would cause it to fail would be great. I pulled the codes an thermostat is fine, but the vacuum pump blew fuse 33. Replaced the fuse and doesn't seem to run when placing key in the ignition.
